Sh2-115 (near Deneb)

[carastro]

Hate this time of the year, my set up is not suited to small galaxies, so started this at around 1am and packed up at 4.30 am !!

I did HOO and added RGB stars, but it was very difficult to extract much Oiii nebulosity as it probably needs a dark location.

An unusual Nebula near Deneb, only seen it imaged once before and needs a lot more data as it's faint and very noisy, but I think I will leave it to a dark location (not sure when that will be or if we ever get a chance this year with the lock down etc etc).  Still at least it is something to do whilst trapped at home.

Atik428EX and SW ED80 + x 0.8 FR
HEQ5
Ha 600 x 13
Oiii 300 x 13 binned
RGB (for stars) - 150 x 3 each channel

Total approx 3 1/2 hours.

Bottom right is a planetary Nebula, I think it is Sh2-116
